Estudio geotécnico in Alhama de Almería

In Alhama de Almería, the dominant geological substrate is made up of limestones, dolomites and marbles, which gives the ground a high bearing capacity ideal for direct foundations in rock. In areas where fine sands and silts appear, a slight reduction in strength and greater compressibility may be observed, so its specific behaviour must be assessed before selecting the most suitable foundation type. The presence of aquifers with moderate permeability should also be considered to avoid problems of transport of fines or seepage in underground works.

The municipality’s seismicity is very low, with only 5 recorded events in the last 30 years and a maximum magnitude of 2.8, so it does not represent a significant constraint for structural design. However, the existence of karst-related phenomena associated with limestones and marbles implies that the presence of cavities must be thoroughly verified before carrying out the foundation. Since the substrate is not clayey, there is no risk of expansivity, and any possible presence of karst is the main constraint for the geotechnical study in Alhama de Almería.
